IMPROVEMENT IN CLOTH-MAPPING MACHINES.

Specification forming part of Letters Patent No To all whom it mayconcern:

' Be it known that I, MARCIENE H. WHIT- 00MB, of Holyoke, Hampdencounty, Massachusetts, have invented a new and Improved Machine for'Nappin g Cloth, of which the following is a specification:

My invention consists of amachine for napping cloth, combining on oneframe the wire or card napper and the teasel-eylinder, the

- object being to have the strength of the Wire or card clothing forbreaking or tearing up the fibers of strong, heavy goods, for which thepower of the teasel is not sufficient, and have the teasels forfinishing the nap, 'for which they are superior to the card.

Figure l is a longitudinal sectional elevation of my improvedcloth-napping machine, taken on line a; a, Fig. 2. Fig. 2 is a plan Viewwith a strip of cloth shown on one side, and Fig. 3 is a detail of themanner of attaching the teasels. V

Similarletters of reference indicate corresponding parts.

A represents the wire or card nappers, and B the teasel-cylinder. Thecloth 0 is first pre- 'sented to the wire nappers and then to theteasels.

The teasels are packed in a frame composed of bars E and F and rodsG,'Which are fastened to the cylinder. I

The small carrying-rollers H are covered with short wire-clothin g, totakestron g hold of the cloth and prevent slipping. The' cloth is drawnover the teasel -cylinder by the large I back roll I, also covered withwire. This combination is employed for very coarse and heavy cloth,which is very. hard to nap, and has always been done on gigs andsinglecylinder nappersmostly on nappers. All manufacturers preferred thegig, but the cloth being so very hard and heavy, it tore the teaselsinpieces, which made it expensive and l77,602,'dated May 16, 1876;application filed March 6, 1876.

a slow process; so they resorted to nappers covered with card-wire. Thenappers reduce the weight of the goods very much more than the teasels,but are quicker.

In this machine I combine the two processes, using the Wire forpreparing the cloth for the 1 teasel, so that it can raise a nap withoutpulling the teasel in ieces, or reducing the Weight of the goods. I saveover any other process of napping over an ounce per yard.

In regard to its capacity, it will be seen that I present the cloth toeach of the napping cylinders twice, and as there are twocylinders, itmakes four touches, and to the tea-sel-cylinder three times. It isperfectly ad-- justable, so that the cloth can beapplied to thecylinders as light or as hard as is desirable,

so that one passage over the machine finishes that side oftbe piece,while on the machines in general use it takes from six to ten runs.

One man on this machine will do the work of. two or three, and it isbetter done, with less waste, and a great saving in room, as thismachine does the Work of eight or ten singlecylinder ones. I

The cost for clothing, teasels, &c., is much less than any other napper.

I propose to employ any arrangement which conducts the cloth fromnapping to teasel cylinders continuously.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of card-nappers A, tease]- eylinderB, and teasels D, the latter packed in a frame, E F G, on the cylinder,substantially as and for the purpose specified.-
